Tooling materials science| Summary: | We pursued the goal of assessing how acceptable the strength criterion of A. Shashenko is for taking into account the physical nonlinearity of sandy loam soils. Theoretical studies of geomechanical processes using analytical and numerical mathematical methods. Analysis and generalization of the results of theoretical research. It is shown that, in the area of experimental data variation, A. Shashenko strength criterion allows one to describe the strength properties of the soil more accurately than the Coulomb–Mohr criterion. It was found that when extrapolating the curves to the region of low pressures, the Coulomb–Mohr strength criterion is the most preferable. For the first time, using specific experimental data, the question of using the strength criterion of A. Shashenko to take into account the physical nonlinearity of the strength properties of sandy loam soil has been investigated. The results obtained by us allow us to reasonably apply A. Shashenko strength criterion to take into account the nonlinear properties of sandy loam soil. |
